Many scholars found there are linear relationships; others assert the relationships are more than complex, and others state there is no link at all between variables. The findings present that there are strong and positive relationship between customer loyalty and its determinants of customer satisfaction, switching costs and trust. Interestingly, switching costs is the strongest variable in explaining the variance of loyalty, other than satisfaction as common believed. However, satisfaction along with trust is still evidence of close link with loyalty. The findings in the research suggest that managers should not ignore any single variable in seeking customer loyalty, instead creating a comprehensive programme to satisfy customer, build switching costs and make customer trust the bank.
